modate the angular position of the stake.

Patented Nov. 29, 1932 UNITED STA TES PATENT OFFICE HARRY E. CHOLFORD, 0F BINGHAMTON, NEW YORK, ASSIGNOR TO BINGHAMTON FOUNDRY & MACHINE CO. INC., OF BINGI-IAMTON, NEW YORK,A CORPORATION OF NEW YORK Application filed May 25,

My invention relates to a stake locking device for road forms or rails and has for its principal object the provision of a self adjusting stake holding member whereby to compensate for any irregular or angular position which the stake may be forced to take when driven into the ground, without disturbing the alignment of the rail.

More specifically my invention contemplates a stake receiving member through which the stakepasses and which is engage able with the upper end of the stake when in its driven position and which is free to rock toward or away from the rail to accom- It should be clearly understood at the outset that there is no lateral movement between the stake and rail provided for, merely an adjustment of the stake locking device to take care of the position of the stake when driven home. 7

Another object of my invention lies in the provision of a novel holder for the stake locking means.

Another object lies in the provision of novel looking or securing means for the stake holding member. I

Other objects and advantages in details of construction and arrangement of parts will be apparent as the description proceeds, reference now being had to the figures of the accompanying drawing forming apart of this application, and in which like reference numerals indicate like parts.

In the drawing:

Figure 2 is a side view of a portion of a rail or form section, illustrating the stake holding and locking means in side elevation.

Figure 3 is a detail cross sectional view taken on the line 33 ofFigure 1. 1

Figure 4 is a detail sectional view taken on the line 4-4: of Figure 2.

My invention is adapted for use withthe common conventional type of road rails or forms usually made of steel and having a substantially channel-like cross section includingthe wide bottom flange 1, the vertical web into the 1931. Serial No. 539,861.

2, the upper horizontal flange 3 and the upper depending flange 4. As is well known these rails or forms are provided in sections or lengths of a desired size for handling, such sections being provided with suitable coupling means (not shown) whereby they may be joined together end to end in use and readily dismantled when the road mate-rial which has been filled in between the parallel forms has become set and hardened.

It is also well known that because of the weight of the road material filled between the parallel forms, and because of the weight of the road processing machinery which must travel thereover, oftentimes upon the rails themselves, said rails must be rigidly secured in proper alignment so that they will not slide or get out of alignment while in user It has been the practice heretofore to provide looking meansin the form of steel stakes driven ground and suitably cooperating with the rail sections to rigidly hold themin position.

A new and improved form of stake locking and holding means forms. the principal subject of this invention and will now be described.

The rail members are provided at intervals along their lengths with laterally disposed anchor plates 5 extending outwardly from the web2 of the rail and at substantially right angles thereto, to a point flush with the outermost end of the lower base flange l. The anchor plates 5 are provided withlaterally extending top, bottom, and side flanges 6, 7, 8, and 9 respectively. These flanges providethe two-fold function of stiffening the anchor plate thereby rendering it strong and rigid, and of providing adequate means for securing the plate to the rail. The side flange 8, and the bottom flange 7 are suitably rigidly secured to the vertical web 2 and the bottomflange 1 of the rail as by welding, riveting, or otherwise as desired. 7

The side flanges 8 and 9 of the anchor plates 5 are cut on a bias fromthe top downwardly as indicated at 10 to provide additional strength and supporting surface for the anchor plate. It will be noted with reference to-Figures land 2 thatthe top of the anchor plate 5 lies below the depending flange 4 of the rail section, it being understood that suitable stif'fening and supporting means for the flanges 3 and 4 of the rail section are provided elsewhere. As this stiffening and supporting means forms no part of this invention, description and disclosure of same has been omitted.

The bottom or base flange 1 of the rail is provided with an opening ll'through which is adapted to pass the steel stake 12 provided for holding the form in alignment. The opening 11 is of the same shape as the stake 12 and only slightly larger in diameter than such stake, whereby any relatively lateral displacement between the rail and stake is prevented although such stake may pass through the opening in any reasonable angular position depending upon the character of the ground into which the stake may be driven. In other words, in driving the stake into the ground it may be deflected from vertical by rocks, etc. and the opening 11, of course, permits such angular displacement of the stake within certain limits.

The anchor plate 5 is provided with an arcuate shaped slot 13 and directly below the lower edge of this slot is provided an arcuate shaped projection or lug 14 either formed from the material of the anchor plate or as a separate lug welded or otherwise secured thereto.

Loosely mounted in the slot 13 and at substantially right angles to the anchor plate 5 is a locking plate 15 provided adjacent one end with an opening 16 through which the stake 12 is adapted to pass closely adjacent the front edge of the top and bottom flanges 6 and 7 of the anchor plate. This locking plate 5 is also provided with an elongated slot 17 extending from the opening 16 to a point adjacent the opposite end of the plate. Slidably disposed within the slot 17 are a pair of oppositely directed wedges 18 and 19 which when driven in opposite directions serve to frictionally bind the stake 12 against the edges of the upper and lower flanges 6 and 7'and the end of the lug 14 onthe anchor plate 5 thereby locking the stake securely against movement and consequently locking the rail in position. The wedges 18 and 19 are provided withpins 20 extending laterally therefrom which prevent'the wedges dropping out of the slot 17 in the locking plate 15. Looking plate 15 is also provided with an upwardly extending lug or car 21 which prevents the locking plate 15 being removed from the arcuate slot 13 in the anchor plate.

It will. be obvious from the foregoing description that with the wedges loosened or in non-binding position, the stake'12 may be driven into the ground and regardless of the angle, within certain limits of course, at which the stake is finally set in the ground, it may be rigidly locked and secured in such position by simply driving the wedges 18 and 19 in opposite directions to provide the binding engagement above described. The arcuate slot 13 in the anchor plate 5 permits the stake 12 to assume the angular position mentioned without disturbing the alignment of the rail itself.

Of course, changes may be made in details of construction and arrangement of parts without departing from the spirit and scope of my invention. I do not limit myself, therefore, to the exact structure herein shown and described other than by the appended claims.
